XPERIA XZ1 Battery draining and getting warm even though when we dont use it

[RizkyRizz]

Im using Xperia XZ1 for 1 month more less

For a couple of weeks it works fine, and then when I was using it for playing a game (LineageII Revolution) it's getting hot and the battery drained so fast, and then I turned off and charged it until full, after that the problem starts until now

The phone is getting warm even though i dont use it, also its getting hot when I charge it, im using QC 3.0 and i also try to not use QC it is UCH20, but its still the same

The battery drains so fast as well, from 4 Or 5 hours for Screen on time, becomes not more than 4 hours 3,5hours more less

I already checked all my app which is running on the background but its useless, i change my phone setting its still the same

And I factory reset twice and it didnt work 

I think the software is broken, and then I Software Repair from Xperia Companion through PC, but it didnt help

I checked my CPU with CPUZ, it should be Deepsleep when I dont use any app and it should be showing 0ghs or sleep status for the CPU Cores, but it shows 300ghz when i dont use any app, it cant sleep until 0ghz

I need help

Sorry for my bad english

Thanks in advance

Hello @RizkyRizz;

It is normal for the phone to get hot when you are playing CPU demanding games, however when on idling for some time it should not be hot depending on ambient temperature. 

Also depending on your installed apps, phone configuration and use it may not be bad 4 hours sot.

Regarding the CPU frequency it is normal for the SD835 showing always 300Mhz on every core even on idle, it never shows 0Mhz (my XZ Premium behaves the same way).

If you already made a repair with XC and it behaves the same way,  if you think it may have a problem (it may not have) the next step is contact your local Xperia support team.

I see so SD835 wont be 0mhz even though we dont use it?

Okay noted

But is it normal if our battery drops every couple hours?

I found it dropped from 100% to 85% when I left my phone at night when i was sleeping, and when I woke up it dropped 15% more less, 1st time when i use XZ1 after I bought it, it worked normaly, i mean the battery is strong, but now I find out it drains easily even after I change my setting, uninstal several app, and Factory reset/Software repair

Before i use XZ1, i was using XZ, and the battery when it was idle, it did not drop easily

I have the same situation with the battery, it falls by 15-17% per night, I do not know what it is connected with, but I suspect that the problem is in the last update.

[RizkyRizz]

Last update?

You mean Security patch for March?

It happens before the update coming tho

I assume that this is about the battery quality, my phone worked fine before its getting hot after i used it for playing game, and maybe the Heat maybe damage the battery

But i check through app and Battery test, and it says my battery is still Good condition, i charge very fast as well when i use QC 3.0

I've changed also several setting to reduce Battery consumption, i uninstal several app as well, only 2 games now in my phone, last time they were 6 games

Any suggestions or thoughts?

47.1.a.12.119 updated today,while I look.

47.1.A.12.75 Here on this firmware I have such an incident, but the battery was not heated. Maybe it's a marriage of batteries?

[RizkyRizz]

Mine is 12.119 Security patch March as well

Btw what do you mean by Marriage of the battery?

Is my battery already broken? 

[Sanya900]

there are cases of marriage, but I do not understand why sony did not say anything.

[Sanya900]

no one answered me, to my request for battery, and to you. Well, it's tech support!
